Efest SLIM K4 Battery Charger | Efest Battery Charger

The Efest SLIM K4 USB Charger is conveniently portable and user-friendly. LED indicators indicate when the changer is in standby mode; charging; or is fully charged. It charges the batteries automatically within a matter of seconds and is designed with both CC and CV-safe battery charge modes. The slots and monitors charge independently. USB-C port reduces the heat while charging.

Superior craftsmanship is evidenced by springs made of piano wire; steel cathode with low resistance and hard chromium plating to achieve a more precise charging voltage; and 15,000+ spring testing for quality assurance.
